>>3650297>But why would you want to?For when you want to shoot with a Leica camera at a given focal length but only have a Nikon lens for that focal length.
E.g., I've got a shitty Sigma 14mm in Nikon mount (which actually has a decent focus distance and DoF scale on it, despite being an autofocus lens) which it might be fun to shoot on my Leica for shits and giggles.
